1). Door Release Trigger (DR). This output goes low when the Door Release switch SW5 is pressed. Note: This is a low going pulse of
a few milliseconds and provides an anti-lockdown circuit. To bypass this circuit and have a permanent trigger when the switch is
pressed move LK6 to ‘Non/RH’ position. For AC/DC Buzzer systems select the ‘Non’ mode.
Note: The handset must be lifted to use the Door Release Button.
2). DC Input (VT). The handset will function with a DC input range between 11-15v DC.
3). 0v Input (0v). The handset is designed to work on systems that use a common ground/0v supply for its reference point.
4). Call Tone or Buzz Input (BZ). The handset will accept various call inputs, a generated tone, 12v AC ring or a 12v DC ring. To use a
generated tone or 12v AC ring LK7 & LK10 jumpers (Call Tone Input Selection 1 & 2) should be set for ED/Tone input. To use 12v DC
ring (using internal piezo buzzer) set LK7 & LK10 to Buzz/RH position.
5). Handset microphone Output (S2). Speech output from handset to the speaker in the front panel.
6). Handset Speaker Input (S1). Speech input from the microphone in the front panel to the handset earpiece.
7). Door Status Input (DS). Input signal from the front door to advise that the door is open and illuminates DS (Green LED). This is
as standard a NO contact at the door when closed. A switched 0v input is set as standard with the jumper links at PL3 linked between
NEG/DS on both sides of PL3 (Switched 0v). A switched 12v input may be used, to do this move both Door Status Input Select Links to
the DS/POS position.
8). Amplified Call Tone Output (EX). The ‘EX’ connection is an amplified version of the call tone input on the ‘BZ’ terminal. It amplifies
the input from 2.5v-12v DC call tone to the voltage available at the handset (11-15v DC). It is imperative that this terminal is only used
to extension sounders, flashing beacons and other AUX equipment including additional handsets added.
9). Call Back (SW4) Output (CB). The ‘CB’ connection is for concierge systems and is used for calling the concierge. This output could
also be used to trigger additional door(s) via timer/relays or trigger other equipment. The output is NO going closed with switched 0V.
10). ‘X’ Connection Throughput (X). The ‘X’ connection is merely a connection point for ease of wiring. It has no connection to any circuitry
on the handset.
11). Alarm Input 11-15v DC (ALM). The ‘ALM’ input is used to sound the internal Piezo sounder when a 11-15v DC input is applied.

GENERAL NOTES
The door entry phone system
is designed so that you have a
limited time to answer a call
and allow the caller access or
not. This is to save inconvenience
to other users of the system.
ON
PRIVACY
ON PRIVACY
DOOR OPEN
1) When called, the telephone will give a distinctive pulsing tone for up to 25
seconds and then stop. You have approx. 30 seconds to answer the call from
the start of the call tone. If the call is not answered within the call period, then
the system will reset to allow other visitors to make a call.
2) To answer the call remove the handset from the cradle and speak to the caller.
(You have approx. 2 minutes to speak to the caller and then the system will
reset).
3) To let the caller gain access, press the lock release button and this will open
the door for approximately 10 seconds.
4) When you have completed the call, replace the handset to reset the system.
PRIVACY SWITCH
5) If you do not wish to be disturbed or annoyed by nuisance calls, press the
privacy switch (the Red LED will illuminate to remind you that the handset is in
privacy mode). When in this mode the call tone is muted until you reset the
switch by pressing it again. If you wish to terminate the privacy period press the
privacy switch once and the Red LED will extinguish.
